This book aims to illustrate with practical examples the applications of linear optimization techniques. It is written in simple and easy tounderstand language and has put together a useful and comprehensive set of worked examples based on real life problems. The topics includelinear programming, integer programming and goal programming. The bookcan be used by teachers, taught-course students and research students of engineering and business/management disciplines. It is, however, not suitable for students of pure mathematics as its emphasis is on applications rather than theories.
